The Net Data Directory is a free, publicly accessible database of information on different sources of data about the Internet. The directory is intended to make finding helpful quantitative data about a broad range of Internet-related topics—broadband, cybersecurity, freedom of expression, and more—easier for researchers, policymakers, journalists, and the public. Users can search, sort, and filter records within this database to identify datasets relevant to their work. The vast majority of datasets within the directory are themselves open and publicly available. Records in the directory include the name of the data source, a short description of the available data, and a link. Data sources are tagged both by geographic coverage (including global, regional, and country-level tags) and by topic (such as broadband, cybersecurity, and social media). This will be added to Statistics Resources and Big Data Subject Tracer™. This will be added to World Wide Web Reference Subject Tracer™. This will be added to Entrepreneurial Resources Subject Tracer™.
